In this work, polyaniline (PANI) nanofibrous networks were prepared using ionic liquid (IL), 1-hexadecyl-3-methylimidazolium chloride (C16MIMCl), as a template through oxidative polymerization of aniline with ammonium persulfate. The resulting PANI was characterized by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-vis, and FTIR. It was indicated that the as-prepared PANI was in the emeraldine form and its morphology strongly depended on the molar ratio of aniline/C16MIMCI. A possible mechanism for the formation of PANI nanofibrous networks was that the ordered micro-domains of the IL acted as template to direct the growth of the nanostructures.
在本工作中，以离子液体（IL）1-十六烷基-3-甲基咪唑氯盐（C16MIMCl）为模板，通过苯胺与过硫酸铵的氧化聚合制备了聚苯胺（PANI）纳米纤维网络。所得聚苯胺通过扫描电子显微镜（SEM）、透射电子显微镜（TEM）、紫外可见光谱和傅里叶变换红外光谱进行表征。结果表明，所制备的聚苯胺为翡翠盐形式，其形态强烈依赖于苯胺/C16MIMCl的摩尔比。聚苯胺纳米纤维网络形成的一种可能机制是，离子液体的有序微区作为模板来指导纳米结构的生长。
